应用场景

VolumeSnapshotClass的名称为csi-dynamic-snapclass-block，PVC的名字为csi-pvc-local，在CSI中创建快照csi-dynamic-snapshot-block-1。

操作步骤

1. 创建VolumeSnapshotClass的YAML配置文件csi-dynamic-snapshot-block-1。

   apiVersion: snapshot.storage.k8s.io/v1
   kind: VolumeSnapshotClass
   metadata:
     name: csi-dynamic-snapclass-block 
   driver: stor.csi.k8s.io
   deletionPolicy: Delete  
   

2. 创建VolumeSnapshot的YAML配置文件csi-dynamic-snapshot-block-1.yaml。

   apiVersion: snapshot.storage.k8s.io/v1
   kind: VolumeSnapshot
   metadata:
     name: csi-dynamic-snapshot-block-1  
   spec:
     volumeSnapshotClassName: csi-dynamic-snapclass-block  
     source:
       persistentVolumeClaimName: csi-pvc-local  
   

3. 应用配置文件VolumeSnapshotClass和VolumeSnapshot的配置文件。

   [root@k8s-master stor-examp]# kubectl apply -f csi-dynamic-snapclass-block-snapshotclass1.yaml
   volumesnapshotclass.snapshot.storage.k8s.io/csi-dynamic-snapclass-block created
   [root@k8s-master stor-examp]# kubectl apply -f csi-dynamic-snapshot-block-1.yaml
   volumesnapshot.snapshot.storage.k8s.io/csi-dynamic-snapshot-block-1 created
   

4. 查看快照。

   [root@k8s-master stor-examp]# kubectl get volumesnapshots csi-dynamic-snapshot-block-1
